What is Grok Imagine 1.5 I2V?
Grok Imagine Video 1.5 Image-to-Video animates a single still into a clip with audio. The output follows your input image's framing — the endpoint has no aspect ratio control — and runs from 1 to 15 seconds at 480p, 720p or 1080p. Billing is per second of output by resolution, plus a small per-image charge for the frame you supply, at the model's cost plus a flat 20% platform fee, shown before you spend. This endpoint animates from a first frame only; it has no end-frame mode, so a first-and-last-frame request is refused rather than silently ignored.
